Early trenches (late 1914) are rarely preserved, but the known archaeological examples in Flanders almost always show a similar pattern. Individual foxholes later joined together to form a continuous trench. Some examples from Wijdendrift (Langermark). #FWW #Archaeology https://t.co/lgJgWIuIAV pic.twitter.com/jyVtxzpXlA
